<p>
Now that we have loaded the iris dataset into H<sub>2</sub>O, we can build a GBM
model.  For this purpose, please use the menu option <span class='label
mref'>Model &gt; GBM</span> or direct <a
href="/2/GBM.query?source=iris.hex&destination_key=model&response=4&ntrees=20&ignore=&learn_rate=0.2"
target="_blank">link</a>.
<p>
</p>
The GBM method has multiple tuning parameters that can affect the model it will
build.  For example, you can increase the number of trees, the maximum tree
depth or the learning rate.
